MainAcitvty 用来视图展示

public class MainActivity extends AppCompatActivity implements ShowContract.ShowView {

    private RecyclerView RecyView;
    private ShowPresenter showPresenter;
    private ShowAdapter showAdapter;
    private DataBeanDao dataBeanDao;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        dataBeanDao = DaoMaster.newDevSession(getBaseContext(), DataBeanDao.TABLENAME).getDataBeanDao();

        RecyView=findViewById(R.id.RecyView);
        if (IfNetWork.isNetworkConnected(this)) {
            HashMap<String,String>  params=new HashMap<>();
            params.put("page","1");
            new ShowPresenter(this).getShowPresneter(params);
        }else{
            List<DataBean> dataBeans = dataBeanDao.loadAll();
            Toast.makeText(getBaseContext(),"没网状态",Toast.LENGTH_LONG).show();
            showAdapter = new ShowAdapter(this, dataBeans);
            RecyView.setLayoutManager(new LinearLayoutManager(this));
            RecyView.setAdapter(showAdapter);
        }
    }

    @Override
    public void Success(List<DataBean> resultBeans) {
        showAdapter = new ShowAdapter(this, resultBeans);
        RecyView.setLayoutManager(new LinearLayoutManager(this));
        RecyView.setAdapter(showAdapter);
        for(int i=0;i<resultBeans.size();i++){
            DataBean dataBean = resultBeans.get(i);
            dataBeanDao.insertOrReplace(new DataBean(i,null,null,null,null,dataBean.getAuthor_name(),null
            ,null,dataBean.getThumbnail_pic_s03()));
        }
    }

    @Override
    public void FailUre(String msg) {

    }
}

api Api 接口

public interface Api {

    @GET
    Call<UserBean> show(@Url String url, @QueryMap HashMap<String,String> params);

}

ApiUrl

public class ApiUrl {
    public static String SHOW="api/news/news.php";
}


Bean类里面


@Entity
public class DataBean {
    @Id
    private long id;

contract

public interface ShowContract {
public abstract class ShowPresenter{
    public abstract void getShowPresneter  (HashMap<String,String>params);

}
    public interface ShowModel{
        void getShowModel(HashMap<String,String> params,ShowModelCallBack showModelCallBack);
    }
    public interface ShowView{
        void Success(List<DataBean> resultBeans);
        void FailUre(String msg);
    }
    public interface ShowModelCallBack{
    void Success(List<DataBean> dataBeanList);
    void FailUre(String msg);
    }

}

model

public class ShowModel implements ShowContract.ShowModel {

    @Override
    public void getShowModel(HashMap<String, String> params, final ShowContract.ShowModelCallBack showModelCallBack) {
        Api api=RetrofitUtils.getInstance().api();
        Call<UserBean> userBeanCall = api.show(ApiUrl.SHOW, params);
        userBeanCall.enqueue(new Callback<UserBean>() {
            @Override
            public void onResponse(Call<UserBean> call, Response<UserBean> response) {
                if (showModelCallBack!=null){
                    if (showModelCallBack!=null){
                        showModelCallBack.Success(response.body().getData());
                    }
                }
            }

            @Override
            public void onFailure(Call<UserBean> call, Throwable t) {
                if (showModelCallBack!=null){
                    showModelCallBack.FailUre(t.getMessage());
                }

            }
        });
    }
}

presenter

public class ShowPresenter extends ShowContract.ShowPresenter {

    private  ShowContract.ShowView showView;
    private ShowModel showModel;

    public ShowPresenter(ShowContract.ShowView showView){
        this.showView=showView;
        showModel = new ShowModel();
    }

    @Override
    public void getShowPresneter(HashMap<String, String> params) {
            showModel.getShowModel(params, new ShowContract.ShowModelCallBack() {
                @Override
                public void Success(List<DataBean> dataBeanList) {
                    showView.Success(dataBeanList);
                }

                @Override
                public void FailUre(String msg) {
                        showView.FailUre(msg);
                }
            });
    }
}

net

public class RetrofitUtils {


    private final Retrofit retrofit;
    private static RetrofitUtils mInstance;

    private RetrofitUtils(){
        HttpLoggingInterceptor httpLoggingInterceptor = new HttpLoggingInterceptor();
        httpLoggingInterceptor.setLevel(HttpLoggingInterceptor.Level.BASIC);
        OkHttpClient okHttpClient=new OkHttpClient.Builder()
                .addInterceptor(httpLoggingInterceptor)
                .addNetworkInterceptor(httpLoggingInterceptor)
                .build();

        retrofit = new Retrofit.Builder()
                .baseUrl("http://www.xieast.com/")
                .addConverterFactory(GsonConverterFactory.create())
                .client(okHttpClient)
                .build();
    }
    public static RetrofitUtils getInstance(){
        if (mInstance==null){
            synchronized (RetrofitUtils.class){
                mInstance = new RetrofitUtils();
            }
        }
        return mInstance;
    }
    public Api api(){
        return retrofit.create(Api.class);
    }
}

自定义缓存路径

public class aaaaa extends Application {
    @Override
    public void onCreate() {
        super.onCreate();
        DiskCacheConfig config = DiskCacheConfig.newBuilder(this)
                .setBaseDirectoryName("images")
                .setBaseDirectoryPath(Environment.getExternalStorageDirectory())
                .build();
        ImagePipelineConfig build = ImagePipelineConfig.newBuilder(this)
                .setMainDiskCacheConfig(config)
                .build();
        Fresco.initialize(this,build);

    }
}

网络判断

public class IfNetWork {
    public static boolean isNetworkConnected(Context context) {
             if (context != null) {
                     ConnectivityManager mConnectivityManager = (ConnectivityManager) context
                             .getSystemService(Context.CONNECTIVITY_SERVICE);
                     NetworkInfo mNetworkInfo = mConnectivityManager.getActiveNetworkInfo();
                     if (mNetworkInfo != null) {
                             return mNetworkInfo.isAvailable();
                         }
                 }
             return false;
         }

}

xml 布局

<android.support.v7.widget.RecyclerView
    android:id="@+id/RecyView"
    android:layout_width="match_parent"
    android:layout_height="match_parent"/>






item
<LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="horizontal"
        >
        <com.facebook.drawee.view.SimpleDraweeView
            android:id="@+id/simpimage"
            android:layout_width="100dp"
            android:layout_height="100dp"
            fresco:roundTopLeft="true"
            fresco:roundBottomLeft="true"
            fresco:roundTopRight="true"
            fresco:roundBottomRight="true"
            fresco:roundedCornerRadius="20dp"
            />
        <TextView
            android:id="@+id/text_id"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_gravity="center"
            android:text="成功就在眼前"
            android:textSize="15sp"
            />

    </LinearLayout>
